    Hi All,
    
    Somewhat off-topic post regarding the upcoming conjunction of
    the sun, moon, Jupiter, Saturn, Mercury, Venus and Mars.  If
    you go to the SOHO LASCO image:

    you can see three of these planets already.  Saturn is at the
    far right, Jupiter is about halfway between Saturn and the
    occulted disk of the sun, and Mercury is by itself on the
    other side.  There are also dozens of 6th, 7th and 8th
    magnitude stars visible in the image.  I have created a
    corresponding image with SkyMap in case anyone wants to
    compare the two.  (Let me know and I'll send you a GIF
    file of the SKYMAP screen capture).
    
    Interestingly, there are some "stars" in the SOHO imagery
    that have no match in Tycho down to 9th magnitude.  Some
    of these are likely gamma or proton hits in the focal plane
    array (there are a few streaks, most notably in the upper
    left corner of the image).  But I suspect that many are
    indeed stars -- hot UV stars that don't show up as bright
    in the visible. --Rob
